For best results, use Blinc mascara on clean and dry lashes - or over the Blinc Lash Primer for extra thickness and length. Within 2 minutes, apply one or more coats. Once set, additional coats cannot be applied. Neither water alone nor pressure alone will remove Blinc mascara. Only the combination of generous amounts of warm water and gentle pressure, from your fingertips or a washcloth, will slide the tiny tubes effortlessly off your lashes into your hand. Blinc mascara does not penetrate your skin or lashes and leaves no tint or residue build-up, making it safe for daily use.
